Answer:
G1 phase cell cycle arrest and apoptosis
Explanation:
According to Yan and colleagues 2009 article, cells that were transfected with microRNA-1/206 showed cell cycle arrest at the G1 phase and showed an increase in apoptosis (programmed cell death) which is important for synthesis of mRNA and protein. These processes have a direct effect on cell proliferation by decreasing it.
